Should a brand consolidate its marketing at one agency or keep a roster of specialists? Two high-profile deals in the past two months point in different directions, yet both reward the same thing: an agency that understands the client well enough to set expectations it can then prove. For agencies chasing big accounts, that is the lesson worth stealing.
The first answer came from StarKist. Marketing Dive reports that the tuna brand consolidated its marketing with independent agency Tombras instead of splitting it across specialist shops. The second came via Adweek, which reports that Stagwell has won ServiceNow in the largest multi-agency deal in its history: a three-year go-to-market partnership in which Stagwell will also roll out ServiceNow's AI platform across its own organisation.
Is agency consolidation back?
It never really left, but it is changing shape. StarKist's version is classic consolidation: one agency, one remit. Marketing Dive lists Tombras's scope as brand strategy, creative development, media planning and buying, organic social and community management, measurement and analytics, and website and SEO assessments.
StarKist's head of marketing and innovation, Michael Merritt, gave two reasons. The brand has "limited resources" and wants to work as efficiently as it can. And once it saw the breadth of the agency's capabilities, "it made a ton of sense to integrate it all." Single-agency consolidation was not the original plan. The agency earned it.
ServiceNow's version is consolidation at holding-company level. Four Stagwell agencies, Code and Theory, 72andSunny, Allison Worldwide and Movers+Shakers, will act as its lead agency partners. COMvergence, cited by Adweek, puts ServiceNow's media spend at $120m, $70m of it held by Dentsu X. And the relationship runs both ways: the client buys services, and the agency group adopts the client's technology.
What are these clients actually buying?
Strip away the announcements and both clients bought the same three things.
- Fewer handovers. Every agency boundary is a place where the brief gets diluted. Dooley Tombras, the agency's president, told Marketing Dive that when creative and social sit together and you are the brand agency, "you know what the brand strategy is."
- Accountability. His other line deserves a place above every agency MD's desk: "When you integrate, and the creative and media are working together, there's nowhere to hide."
- Evidence of judgement. Tombras points to its MoonPie work, which used Congressional hearings on unexplained aerial phenomena to make the snack brand the first to pitch to aliens and generated over a billion earned media impressions. Stagwell is rolling out ServiceNow's AI platform across its own organisation. One is proof of cultural instinct, the other proof of commitment.
Why do clients consolidate, and why do they leave?
Expectation Confirmation Theory, borrowed from consumer research, explains a lot of client behaviour. Satisfaction does not depend on absolute performance. It depends on performance compared with what you were led to expect. Beat the expectation and loyalty grows. Fall short and even good work feels like failure.
Consolidation raises the stakes on both sides. A client who hands one agency the whole remit has formed a big expectation: fewer handovers, faster response, one accountable partner. If the first quarter confirms it, the relationship compounds. If it does not, there is nowhere to hide and no other agency to blame.
This is why understanding is the foundation of connection. The agencies that keep big accounts are not the ones that promise most in the pitch. They are the ones whose promises rest on a real understanding of the client's audience and category, so the expectations they set are ones they can actually confirm.
Consolidation, roster or holdco team: which model wins big accounts?
| Model | Recent example | What the client gets | What the agency must prove |
|---|---|---|---|
| Single integrated agency | StarKist and Tombras | One strategy, one team, fewer handovers | Breadth across disciplines and accountability for the whole result |
| Holding-company team | ServiceNow and Stagwell | Several specialist agencies under one commercial umbrella | That several agencies behave, and measure, like one |
| Specialist roster | The traditional default for many large advertisers | Deep expertise in each discipline | Clear value in its own lane, and a willingness to collaborate with rivals |
No model wins by default. What wins is the agency that makes its model's promise measurable. An integrated agency must show the integration paying off. A holdco team must show it is more than several invoices stapled together. A specialist must show its lane genuinely moves the result.
How do you build a case study a consolidating client will believe?
Marketers researching a review read case studies the way buyers read reviews: looking for evidence that the result will repeat. Here is how to set up a piece of work so it becomes one.
- Write the client's expectation down in their words. "Grow consideration among under-35s" is a different promise from "sell more tins". Agree which one you will be judged on.
- Ground the strategy in real behaviour. Build the audience view from what people and competitors actually publish, not only from surveys, so the insight survives scrutiny.
- Pre-test before you spend. Score creative options before media money goes behind them, so the first results confirm the plan rather than embarrass it.
- Agree one measurement framework across disciplines. If creative, media and social each report different numbers, the client will believe the worst one.
- Set 30, 60 and 90-day checkpoints. Early confirmation of small expectations buys patience for the big ones.
- Report against the original promise. Not against new metrics chosen after the fact. Clients notice.
- Document the chain. Insight, decision, creative, media, result. That chain is the case study.
Step three is where predictive tools earn their place. Defy's predictions are validated against real ad performance, so the outcome conversation with a client can start from evidence rather than optimism. You can see how that sits alongside competitor and audience intelligence on the Defy platform.
What should independent agencies take from this?
Two things. First, StarKist is a reminder that an independent can win a full remit from a well-known brand when it demonstrates breadth. Independence is not a ceiling on scope.
Second, ServiceNow shows how big-account wins are increasingly tied to technology. Few independents can offer a client a group-wide platform commitment on that scale. What they can offer is speed, senior attention and evidence: a clear view of the client's category from real data, creative tested before spend and reporting that confirms what the pitch promised.
Clients do not reward the biggest promise. They reward the promise that comes true.
